Specification of Letters Patent.

Patented Dec. 9,1919.

Application filed February 9, 1918. Serial No. 216,318

To all whom it may concern:

Be it known that I, EDGAR G. AN'ri-mxr, a citizen of the United-States, residing at. New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Calendars, of which the following is a specification.

This invention relates to a calendar in which the data are simply and conveniently assembled.

This invention has for its object the production of a calendar in which the data showing the days of the weeks, the months of the years, and years are arranged so as to facilitate the ascertainment in advance of any date. A

For a clearer understanding of the invention, reference is made to the accompanying drawings, in which- Figure l is a plan view of a calendar showing one method of presenting the calandar-data.

Fig. 2 is a side view of the same.

Fig. 3 is a plan view showing another method of presenting the calendar-data.

As shown in Figs. 1 and 2, the calendar comprises a circular disk 1 on which the data hereinafter described, is assembled, pivotally attached to a backing-piece 2, a leg 3 attached to the' backing-piece 2 and supporting the same and a day indicator A attached to the backing-piece 2. As shown in Fig. 1, the seven days of the week are assembled around a seven-pointed star. Between consecutive points of the star extending radiatingly are number-columns 6, 7, 8, 9, 10, 11 and 12, at the outer extremities of which are the years corresponding thereto. Adjacent to nuinber-column 6 are assembled in radiating column-form 21, the months of the year. The particular arrangement of the data is shown forall the days ofthe week, the appropriate data for one day only, Sunday, being filled in. In the form of calendar presented, days of particular importance may be shown on the interior of the star, and as an example of such, Easter Sunday is given for seven consecutive years.

As shown in Fig. 3, the data are assembled in a form convenient -to be used as a wall-calendar. Taking Sunday as an eX- ample, the dates for all Sundays in 1917 are assembled in column 13, for 1918 in column 14, and so on. The months of the year are assembled in column-form 20 adjacent the number-column 19. At the head of each number-column is arranged the year corresponding thereto.

The facility with which any particular date can b e determined is illustrated by the following example: Suppose it is desirable to know the date of the fourth Sunday in April, 1918. Referring to Fig. 1, the disk 1 is rotated until the day Sunday swings bencath the day-indicator i. Turning to the month-column 21, the month April is located and on a line therewith in the numbercolumn 7 corresponding to the year 1918, the number 28 corresponding to the day aforesaid.

The calendar as presented is known as a seven-day seven-cycle calendar, the data being assembled for seven years. Each year a new calendar may be issued, the calendar always containing the data for seven years.

The data as arranged presents an easy, simple and convenient method for determining the date of any day in advance that is within the compass 0f the calendar, and is of the greatest help to business firms desiring such information quickly.

The data assembled` in Fig. 3 instead of being in the form of a wall-calendar may be bound in book-form, each page containing one day of the week. Assembled in this manner it may be easily and conveniently carried about in a persons pocket, being always at his command when needed.

I claim 1. A calendar having marked thereon seven areas, one for each day of the week, each area divided into columns, one for each of a number of years, each column having spaces for day-of-the-week dates, and having thereon appropriately arranged designations for years, months and days of the week. A

2. A calendar having marked thereon seven sector-shaped areas, one for each 'day of the week, each area divided into columns, one for each of anumber of years, each column having spaces for day-of-the-week dates, and having thereon appropriately arranged designations for the years, months and days of the week.

3. A calendar comprising a rotatably supported disk having marked thereon sectorshaped areas, one for each day of the week, each divided into columns, one for each of a number of years, each column having spaces for day-of-the-week dates, and having thereon appropriately arranged designations for the years, months and days of the week and an indicator fixed to the disk support.

4. A calendar having marked thereon seven sector-shaped areas, one for each day of the Week, each area divided into rolumns, one for each of a number of years, each roiumn having spaces for day-ot`the-week dates, appropriately arranged designations for the years, months and days of the Week Within said areas and special day spaces on the area inelosed by said sector-shaped 5. A calendar having marked thereon seven sector-shaped areas, one for each day of the Week, each area divided into Columns, one for each of a number ot' years, the year designations being at the outer extremities of said columns, each column having spaces for day-of-the-Week dates and havingthereon appropriately arranged designations for the months and days otA the week.

In testimony whereoiC I aiiX my signature.
